ROTATABLE DUAL-PURPOSE AXIAL-FLOW BLOWER/VACUUM

WIPO Patent Application WO/2023/155253

A1

The present invention provides a rotatable dual-purpose axial-flow blower/vacuum, comprising a main machine housing and an airflow driving device provided in the main machine housing, an air suction transition joint being provided on one end of the main machine housing, and an air blowing portion being provided on the other end, and further comprising a handle connected to the main machine housing, a switch for controlling the start/stop of blowing/suction being provided on the handle. A rotating structure is provided between the main machine housing and the handle; the rotating structure is provided with a rotating locking structure; when the rotating locking structure is pressed, the main machine housing can be rotated to enable the air suction transition joint to face forwards, and the axial-flow blower/vacuum is configured to be in a dust collection mode; and the main machine housing is rotated to enable the air blowing portion to face forwards, and the axial-flow blower/vacuum is configured to be in an air blowing mode. The direction of the main machine housing is rotated, such that two functions of dust collection and air blowing are achieved, the control circuit is simplified, and the ergonomic design is met.
